A bird is sitting on a train A moving at a speed of 40 kmph. It sees another train B at a Distance of 200 ms with Speed of 60 km

Aloiza [94]

Solution:

Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.
Hope it helps

What is the frequency of the sinusoidal graph?

FrozenT [24]

Answer:

$\boxed{f=\dfrac{3}{2\pi}}.$

Step-by-step explanation:

Notice that the wave completes 3 oscillations at $x=2\pi$ . This means that the period is:

$T = \dfrac{2\pi}{3}.$

Since the frequency is the reciprocal of the period, we get:

$f= \dfrac{1}{T} = \dfrac{1}{2\pi/3} = \dfrac{3}{2\pi}.$

So the frequency is:

$\boxed{f=\dfrac{3}{2\pi}}.$

When choosing a new class color, 90 students voted for crimson and 60 voted for royal blue. What percent of these students voted

neonofarm [45]

The percentage of students voted for colour crimson
=
$\frac{90}{60 + 90} \times 100\% \\ = \frac{90}{150} \times 100\%\\ = \frac{9}{15} \times 100\% \\ = 60\%$
hope it helps!
